Please help. I just want to know if i can configure my lancard with two ip address without any conflict to each other address.. We have a lan and an internet connection and a server used as a domain on our lan.. If the network address of our lan is 192.168.0.0 and the network address of our internet is 192.168.2.0, how can i connect to our lan without disconnecting the internet connection? can i have an internet connection and the same time connected to our lan on just one lancard?

You can't assign more than one IP to a network connection.

Firstly, you'll need to make things a little clearer. Are you attempting to add internet access to your private network? Plus, the network address of the internet connection (192.168.2.x) makes me think that you are trying to route between your network and another private network (with it's own internet access). Is this correct?
